Valve\u2019s next major SteamOS update brings some significant new display settings as well as some new performance improvements to Steam Deck. You can read all about the SteamOS 3.5 update in a blog post on the Steam website<\/a>.<\/p>\n<\/div>\n Two major new features are support for variable refresh rates (VRR) and HDR if you\u2019re using your Steam Deck with an external display that supports them. Valve says that HDR can be enabled if you have a compatible display while VRR can be enabled if you have a compatible USB-C adapter. <\/p>\n<\/div>\n The company has also changed the Steam Deck\u2019s default color rendering to \u201cemulate the sRGB color gamut,\u201d which Valve says will result in \u201ca slightly warmer and more vibrant color appearance.\u201d If you don\u2019t like the change, or want to try one of your own, Valve has also added settings that let you tweak the display\u2019s color vibrancy and color temperature.<\/p>\n<\/div>\n There are some welcome changes that aren\u2019t related to display settings, too. The update includes \u201cupdated graphics drivers, with many performance and functionality improvements.\u201d Valve says the update brings \u201cimproved performance for Starfield<\/em>;\u201d Bethesda\u2019s excellent space RPG isn\u2019t verified for Steam Deck, but that hasn\u2019t stopped people from playing the game on the handheld gaming PC anyway<\/a>.<\/p>\n<\/div>\n Valve also promises that the new update adds \u201cslightly improved sleep resume speed.\u201d Every second helps!<\/p>\n<\/div>\n And for Linux desktop mode users of the Steam Deck, the underlying Arch Linux has been updated, complete with a new version of the Plasma desktop interface with an updated Discover app store, widgets, and a new window tiling system. <\/p>\n<\/div>\n The BIOS also has \u201cvoltage offset settings\u201d now, which we take to mean you can more easily undervolt or overclock the Steam Deck but we\u2019ll have to check to be sure.<\/p>\n<\/div>\n If you want to try the SteamOS 3.5 preview, go to Settings > System > System Update Channel > Preview. If the preview is too unstable for you, you can always switch back to the Stable channel.<\/p>\n<\/div>\n
